Benthic State and Change in UK Marine waters. English Channel benthic sampling 2005 dataset https://portal.medin.org.uk/portal/start.php?tpc=009_CEFAS5bda80e5-9d81-4d90-bc8f-dc1c844fa1db Sampling of the biological and physical characteristics of 155 stations in the English Channel, Celtic Seas and the North Sea. This data is specifically from the English Channel samples, collected in 2005 and details the abundance of macrofauna found in each sample. Environmental variables quantified for each station included bathymetry (except North Sea and western Scotland), stratification, bottom temperature and a number of derived granulometric parameters (e.g., % silt, % gravel, sorting coefficient, skewness, kurtosis), together with modelled parameters such as bed tidal stress, wave stress, bottom temperature, a stratification index and satellite-derived surface chlorophyll a (mean values for 2002-07 used). Estimates of the benthic productivity associated with such communities were also derived, for the first time, at this large spatial scale. 20200717 20200627
